Application med April s, 1924. serial ivo/704,979.

To all whom t may concern.'

Be it known that I, FRANK J. Ciascuna citizen of the United States,residing at Cuyahoga Falls, in the county of Summit and' State of Ohio,have invented ycertain new and useful Improvements in Nursing Bottles,of which the following is a specification, reference being had thereintothe accompanying drawing. y

This invention relates to certain new and useful improvements innursingl bottles,.the object being to provide a botti which` is soconstructed that air Will be admitted into the bottle, as the milk isdrawn out through the nipple so as to prevent a'vacuum from beingformed, thereby overcoming the difliculties existing with thenursingb'ottles now in use. v

Another and further object of the invention is to provide a bottle withavent closed by a flexible member which is so constructed that it snuglyfits the neck of the kbottle so as to prevent the milk from passing' outthrough the vent yet allows air to passin through the vent into thebottle as the milk is withdrawn.

Other and further objects and advantages of the invention will behereinafter setV forth and the novel features thereof deined by theappended claims.

In the drawing I have shown aY side ele vation of a nursing bottle,partly in section, illustrating one embodiment of my invention and whileI have shown a specially shaped bottle, it is, of course, understoodthat I do not wish to limit myself to any particular shape of bottle orthe number of vents used.

In carrying out; my invention I employ a bottle, preferably vformed ofglass, comprisfrom the shoulder of the bottle to the mouth of theneckand is provided with an interior annular groove for the purposehereinafter fully described. 1

The neck of the bottle is provided with an air vent 3, the outer wall ofthe neck being enlarged around the vent as clearly shown, but it is,ofcourse, understood that this is not essential and the outer wall ofthe neck might be provided with an annular rib through which the Vventor vents could extend.

- Arranged within the neck of the bottle 'is a rubber sleeve 4 providedwith an enlarged bottle.

ing a body l having a neck 2 which tapersupper edge forming ,anIVannular bead adapted lto be seated in the annular groove formed intheneck of the. `bottleliat the mouth. f The sleeve slightly tapers fromthe bead orl uppery edgetowards the lower edge thereof andisada'pted-lto vfit snugly'withm the neck of the bottle.

The sleeve is inserted from the top and as the neck gradually tapers, itfits snugly the interior of the neck at thek junction of the body sothat the contents of the bottle is prevented sleeve. l

The tube collapses so as to allow air to en-y ter the vent and Anordinary nipple 6 can Abe used and as the milk is drawn out of thebottle through j i i the nipple, the sleeve yields in order to allow airto pass vthrough the vent Vinto the passinto the interior of the frompassing out around the body ofv the bottle which prevents the nip;

yple from collapsing, thereby overcomingthe y y, driculties nowexisting'wlth nursing. bottles.

F rom the foregoingdescription it will be lseen that I have provided ay'nursing bottle'- with a neckhaving a vent. in the kwall thereof l overwhich-isarranged a rubber sleeve hav-y ing an annularv bead at itsupper` edge to reinforce the same to facilitate the insertion f of thesleeve within the neck, whereby a bottle is constructed which allows airto enterl the same as the contents -is drawn out.

'Ihev sleeve can be readily removed and the bottle sterilized in theordinary manner, the sleeve` being alsosterilized so that -a thoroughlysanitary bottle .is formed and as the Vvent hole is protected by thesleeve,.it

is never exposed to the contents of the bottle.

As the contents ofthe bottle is withdrawn through the nipple, a partialvacuum is cre# f ated within the bottle and the rubber sleeve collapsesslightly` so as to allow airto come in through the Avent hole. i

What I claim. is: v LA nursing bottle providedwith a neck havinga. ventin the wall thereof and a flexi- Y ble sleeve arranged within the neckof the bottle over said vent and fornring a valveV for said vent.

2. A nursing bottle having a taperingV neck. provided with' a vent and aflexible rubber sleeve arranged withinV said neck over said 'vent andforming alvalve forl said vent.

3. A nursing bottle having a vent and a rubber sleeve arranged over saidvent to 'form a valve for said vent and so constructed that the contentsof, the bottle passes th-rough'said sleeve and the valve. opens to allowair to enter said bottle through said vent When a partial vacuum iscreated therein. l

4;. As a new artiole of manufacture, a ni'irsing bottle havingaftapering -neck .pro-

vided "With a vent inthe Wall thereof, a ruloloer sleeve IarrangedWithin the neck of saidbottle extending from the mouth of `the neck to apoint beyond the vent rand forming a, valve forfsaid vent.
